ABSTRACT

A music practice feedback method, system, and non-transitory computer readable medium including a displaying device configured to display sheet music, a collecting device configured to collect information related to a playing of the sheet music by a plurality of players, and a display changing device configured to change a display of the sheet music based on said collected information.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a Continuation Application of U.S. patentapplication Ser. No. 14/985,160, filed on Dec. 30, 2015, the entirecontents of which are hereby incorporated by reference.

BACKGROUND

The present invention relates generally to a music practice feedbacksystem, and more particularly, but not by way of limitation, to a musicpractice feedback system for changing a visualization of sheet musicbased on collecting of information related to the playing of regions ofthe sheet music.

Conventional techniques for visualization of music and other sounds usenote extraction. The conventional techniques may label the twelve notesof an octave around a circle. Raw audio information is fed into thesystem, whereby the system applies note extraction techniques to isolatethe musical notes in a particular passage. The intervals between thenotes are then visualized by displaying a line between the labelscorresponding to the note labels on the circle. Further, the linesrepresenting the intervals are color coded with a different color foreach of the six intervals. Also, the music and other sounds arevisualized upon a helix that allows an indication of absolute frequencyto be displayed for each note or sound. However, these conventionaltechniques merely label parts of the music without identifying any otherinformation about the regions.

Other conventional techniques accelerate conceptual comprehension inlearning and technical proficiency in performing a musical piece orlesson by identifying performance issues with particular musicalconcepts. Based on this identification, customized lessons are createdthat focus on the improvement of these specific musical concepts. Thus,through the iteration, a series of lessons is dynamically generatedbased specifically on the user's performance. However, this techniqueonly generates lessons for complex musical concepts and it not directedtowards actual musical pieces. Therefore, although the techniquesattempt to teach users complex musical concepts, the complex musicalconcepts are artificially generated and not necessary included in sheetmusic as the same concept.

Thus, there is a technical problem in the conventional techniques thatthe techniques are incapable of providing a music practice feedbacksystem that can identify difficult regions of sheet music based on acollection of information such that the users can focus their practiceon these difficult areas without the need for a teacher.

DETAILED DESCRIPTION

The invention will now be described with reference to FIGS. 1-5, inwhich like reference numerals refer to like parts throughout. It isemphasized that, according to common practice, the various features ofthe drawing are not necessarily to scale. On the contrary, thedimensions of the various features can be arbitrarily expanded orreduced for clarity. Exemplary embodiments are provided below forillustration purposes and do not limit the claims.

With reference now to FIG. 1, the music practice feedback system 100includes a displaying device 101, a collecting device 102, a displaychanging device 103, a prediction device 104, a difficulty calculatingdevice 105, a similarity detection device 106, a calendar reading device107, a point calculating device 108, and a classification device 109.The music practice feedback system 100 includes a processor 180 and amemory 190, with the memory 190 storing instructions to cause theprocessor 180 to execute each device of music practice feedback system100.

Although the music practice feedback system 100 includes variousdevices, it should be noted that a music practice feedback system caninclude modules in which the memory 190 stores instructions to cause theprocessor 180 to execute each module of music practice feedback system100.

With the use of these various devices, the music practice feedbacksystem 100 may act in a more sophisticated and useful fashion, and in acognitive manner while giving the impression of mental abilities andprocesses related to knowledge, attention, memory, judgment andevaluation, reasoning, and advanced computation. That is, a system issaid to be “cognitive” if it possesses macro-scaleproperties—perception, goal-oriented behavior, learning/memory andaction—that characterize systems (i.e., humans) that all agree arecognitive.

Although as shown in FIGS. 3-5 and as described later, the computersystem/server 12 is exemplarily shown in cloud computing node 10 as ageneral-purpose computing device which may execute in a layer the musicpractice feedback system 100 (FIG. 5), it is noted that the presentinvention can be implemented outside of the cloud environment.

The displaying device 101 displays sheet music that is split intoregions. The regions include sections of the sheet music based on anyone of time to play, difficulty, part of the sheet music, etc.

It is noted that the term “sheet music” is not limited to an actualpiece of paper including music but includes any musical representationthat can be read by a user and displayed. Accordingly, the displayingdevice 101 is configured to display music in any faun that is able to beread and practiced by an individual

The collecting device 102 collects information related to the playing ofregions of the sheet music. The collecting device 102 collects theinformation and pairs it to a particular regions. The information can befor a single musician, or, more preferably for a plurality of musicians(i.e., cohorts of musicians/players).

The information can include difficulties that an individual or crowdhave with certain regions of the sheet music (or that are predicted tohave), difficulties that cohorts of players have with certain regions ofthe sheet music, a measure of playing improvement of the user of thesystem 100, a measure of playing decline of the user of the system 100(e.g., “decay” through time), information on a region in whichcreativity injection (e.g., improvisation) is useful, and a measure ofan emotional response to a region, etc.

The cohorts of players relates to, for example, people of certain agesand geographies, people with certain finger lengths, people withdifferent experiences and educational levels, people with certaindisease states (e.g. Parkinson's, Alzheimer's, Dystonia, Carpal TunnelSyndrome), etc.

The information also can include a determination factor of musicalplaying quality which takes into consideration timing and frequency ormissing of the correct notes. The determination factor includes in theinformation collected by the collection device 102 may involvecomputation of a multidimensional decay surface signifying differentdecay rates for different classes of playing characteristics. As anexample, for different songs and regions of the score, a user's abilityto retain playing skills may decay at different rates, and a forecastmay be made and/or learned via machine learning.

Based on the determination factor included in the information, a skilldecay curve, and on the measured level of skill and achievement for agiven sheet music, training help can be generated. For example, astudent can be prompted to practice difficult regions, and then directedto practice remaining regions of the sheet music. Additionally, astudent might be prompted to practice, for example, 5-10 mins a segmenthe is having difficulty with outside of the regular practice period toimprove overall progress with the sheet music.

The display changing device 103 changes the visual display of theregions of the sheet music based on the info Illation collected by thecollecting device 102. The visualization change can be any change suchthat it draws the user's attention thereto in order to increase theuser's practice rate of the region. Typically, the display changingdevice 103 changes the display of a region based on the difficulty ofthe region as determined from the collected information. However, thedisplay changing device 103 can change the display of a region of thesheet music based on any set of collected information.

That is, teachers typically teach students to practice the challengingparts first before start practicing the entire piece. This would be anexample of a reason for parents to seek an experienced teacher. However,based on the analysis of the how well students play certain parts of apiece, the display device 103 can automatically identify challengingregions and highlight (or use other visualization mechanisms to drawattention to) those regions.

The prediction device 104 predicts a user's advancement or decline basedon how much the user practices the regions that have been displayeddifferently by the display changing device 103. For example, theprediction device 104 can make a localized prediction (i.e., playerdecline or advancement) based on playing by one or more individuals(e.g. a region in which additional practice is likely to be needed aftertime T=1 week, 2 weeks, and 1 month).

The difficultly calculating device 105 calculates a “difficulty” or ameasure of student error of a particular region of the sheet music basedon a distance of a student performance from a target playing (includingincorrect notes, pitches, rhythms, vibrato, etc). The display changingdevice 103 can change the display when the difficulty calculating device105 calculates that the difficulty of the region is greater than apredetermined threshold. For example, if 90% of students have errors ina region of music as calculated by the difficultly calculating device105, the display device 103 changes the display of that region.

The similarity detecting device 106 detects a similarity with thecurrent user's playstyle to other users in the cohorts of players. Forexample, difficulties in regions of the sheet music may be used to aidin the assessment of possible diseases and their decline pathways (e.g.Parkinson's, Alzheimer's, Dystonia, Carpal Tunnel Syndrome) based on asimilarity between the current user and other users with the particulardiseases.

A bidirectional feed from an electronic calendar be used to assessfatigue, musical workout routines, etc., and be used to shape targetcurves (e.g. musical scores) and also schedule future musical workoutsby the calendar reading device 107. The calendar reading device 107facilitates planning, schedules, being easier on the student when aschedule is packed with activities, etc.

The point calculating device 108 rewards and incentives (e.g. calculate“points,” accesses to more sheets of music, access to special orrestricted functions) may be provided by “the crowd” (e.g., livelisteners), by the system 100, by a social network, etc.

The classification device 109 classifies the user into a specific groupof users based on their playstyle. For example, the classificationdevice 109 can automatically classify a user into a geographical region,an age bracket, a skill level, etc. The classifications can be used tocompare the groups with each other to find differences in each group.For example, potentially 16 to 20 year olds have great difficulty with aparticular region but 80-year-olds play the particular region with ease.This data can be used by an external source to determine patterns.

In conjunction with the music practice feedback system 100, variousinput methods (such as microphone) on devices can be used to capture thesound of playing instruments. Alternatively, electronic instruments withMIDI (Musical Instrument Digital Interface) and related interfaces canbe used for many classes of musical instruments. Also, the useroptionally provides various information to tailor the music practicefeedback system 100 to his/her needs, and/or the music practice feedbacksystem 100 may be determine some of these aspects in an automaticmanner, with a certain degree of confidence. The example informationthat a user can provide includes age, how many year he/she has beenplaying, type of instrument, typical duration and frequency of practice,and other cohort information including geographies (e.g. Korea, China,New York, etc.), experience levels, cognitive characteristics (e.g. aperson who is easily distracted, who practices for a certain amount oftime and appears to enjoy it, various characteristics based on facialexpression analysis, etc.), etc. Also, existing basic components can beleveraged in analyzing the input data. For example, the system usesmetronome for rhythm and tuner for pitch. The music practice feedbacksystem 100 analyze the difference between what is supposed to sound likebased on the music score versus how the person is playing or how thecohorts of people played the music piece.

In one embodiment, the music practice feedback system 100 canautomatically monitor the outcomes of music practice, and based on suchoutcomes, the system can offered suggestions for teachers, practicing,etc. In one embodiment, the process may involve automated measures ofwork product (musical output) complexity, difficulty and quality, alongwith assessments of an expertise/proficiency level that has beenattained in order to produce the work product (musical output). Forexample, for playing certain pieces, there are specific mathematicalmeasures that characterize work product (musical output) quality andsophistication, and thus the system can make an assessment of the musicmade by a user in various automated manners.

FIG. 2 shows a high level flow chart for a method 200 of music practicefeedback.

Step 201 displays sheet music.

Step 202 collects information related to the playing of regions of thesheet music displayed in Step 201.

Step 203 changes the visual display of the regions of the sheet musicbased on the information collected by step 202.

Step 204 predicts a user's advancement or decline based on how much theuser practices the regions that have been displayed differently by step203.

Step 205 calculates a “difficulty” or a measure of student error of aparticular region of the sheet music based on a distance of a studentperformance from a target playing (including incorrect notes, pitches,rhythms, vibrato, etc).

Step 206 detects a similarity with the current user's playstyle to otherusers in the cohorts of players.

Step 207 uses a bidirectional feed from an electronic calendar to assessfatigue, musical workout routines, etc., and to shape target curves(e.g. musical scores) and also schedule future musical workouts.

Step 208 rewards and incentives (e.g. calculate “points,” accesses tomore sheets of music, access to special or restricted functions) basedon “the crowd” (e.g., live listeners), by the system 100, by a socialnetwork, etc.

Step 209 classifies the user into a specific group of users based ontheir playstyle.

Exemplary Hardware Aspects, Using a Cloud Computing Environment

It is understood in advance that although this disclosure includes adetailed description on cloud computing, implementation of the teachingsrecited herein are not limited to a cloud computing environment. Rather,embodiments of the present invention are capable of being implemented inconjunction with any other type of computing environment now known orlater developed.

Cloud computing is a model of service delivery for enabling convenient,on-demand network access to a shared pool of configurable computingresources (e.g. networks, network bandwidth, servers, processing,memory, storage, applications, virtual machines, and services) that canbe rapidly provisioned and released with minimal management effort orinteraction with a provider of the service. This cloud model may includeat least five characteristics, at least three service models, and atleast four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provisioncomputing capabilities, such as server time and network storage, asneeded automatically without requiring human interaction with theservice's provider.

Broad network access: capabilities are available over a network andaccessed through standard mechanisms that promote use by heterogeneousthin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to servemultiple consumers using a multi-tenant model, with different physicaland virtual resources dynamically assigned and reassigned according todemand. There is a sense of location independence in that the consumergenerally has no control or knowledge over the exact location of theprovided resources but may be able to specify location at a higher levelof abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elasticallyprovisioned, in some cases automatically, to quickly scale out andrapidly released to quickly scale in. To the consumer, the capabilitiesavailable for provisioning often appear to be unlimited and can bepurchased in any quantity at any time.

Measured service: cloud systems automatically control and optimizeresource use by leveraging a metering capability at some level ofabstraction appropriate to the type of service (e.g., storage,processing, bandwidth, and active user accounts). Resource usage can bemonitored, controlled, and reported providing transparency for both theprovider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer isto use the provider's applications running on a cloud infrastructure.The applications are accessible from various client devices through athin client interface such as a web browser (e.g., web-based e-mail).The consumer does not manage or control the underlying cloudinfrastructure including network, servers, operating systems, storage,or even individual application capabilities, with the possible exceptionof limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer isto deploy onto the cloud infrastructure consumer-created or acquiredapplications created using programming languages and tools supported bythe provider. The consumer does not manage or control the underlyingcloud infrastructure including networks, servers, operating systems, orstorage, but has control over the deployed applications and possiblyapplication hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to theconsumer is to provision processing, storage, networks, and otherfundamental computing resources where the consumer is able to deploy andrun arbitrary software, which can include operating systems andapplications. The consumer does not manage or control the underlyingcloud infrastructure but has control over operating systems, storage,deployed applications, and possibly limited control of select networkingcomponents (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for anorganization. It may be managed by the organization or a third party andmay exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by severalorganizations and supports a specific community that has shared concerns(e.g., mission, security requirements, policy, and complianceconsiderations). It may be managed by the organizations or a third partyand may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the generalpublic or a large industry group and is owned by an organization sellingcloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or moreclouds (private, community, or public) that remain unique entities butare bound together by standardized or proprietary technology thatenables data and application portability (e.g., cloud bursting forload-balancing between clouds).

A cloud computing environment is service oriented with a focus onstatelessness, low coupling, modularity, and semantic interoperability.At the heart of cloud computing is an infrastructure comprising anetwork of interconnected nodes.
